The class will begin with an informal discussion reviewing yesterday's lesson and lab. They will then split up into the same lab groups from yesterday to demonstrate their complete understanding of basic genetics through the "What are the Odds?" lab. A discussion using the knowledge taken from completion of this lab as well as their hypotheses from the Gene in a Bottle lab will prepare the class for the introduction and explanation of lesson 3, meiosis. Students will learn the key aspects of meiosis as it applies to inheritance.
-Make sure that all computers have Faces program installed prior to the lesson.
Opening
To begin the lesson students will be asked about what they think their lab from yesterday will be accomplishing. Students will check on the status of their plants and if there has been any growth. If there has been growth, students will record the number of white and green stalks into their observations.
Activities
Students will then split up into the same lab groups from yesterday to demonstrate their complete understanding through the "What are the Odds?" lab. This lab focuses on the influence of dominant and recessive genes, and their affect on the development of phenotype. Using coins as an odds maker, students will flip and record their results for each facial trait. These traits will be recorded using a program called faces, that is pre-downloaded onto computers. Students will match their results as closely as possible on the program in order to create their "baby". Once they have their final result, students will print out 2 copies of their creation: one to be handed in and graded, and one to take home. The knowledge gained from completion of this lab and the work from the Gene in a Bottle will pave the way into the lecture and notes on meiosis. Students will take notes on the stages of meiosis and how genes are crossed over so that variation in genotype can occur. I will emphasize how genotype directly effects phenotype in hopes that the students will form meaning and make connections between meiosis and the two labs they have been working on. They will further understand the direct correlation between meiosis as it applies to inheritance.
Closing/postlab
I will be grading students based on the accuracy of their baby, compared to the results that they observed when flipping the coins. I will also formatively grade students based
